Introduction
     You have been hired by the school district as a network consultant.  Your mission is to present the School Board with a comprehensive network infrastructure for the High School.

Task
Research current networking technologies from reliable sources. Design a network for the following situation:
  • 3 Computer labs: 25 machines in each, with 1 Printer
  • 3 Computers in each room
  • Design wiring closets for salability and management.
  • Decide what networking equipment is required in each lab, room, wiring closet.
  • Sketch Network layout.
  • Presentation of equipment needs and justification of infrastructure design.

Process
Step 1 - Basics
  • Go to  K-12 Networking and find what the three basic components of a network are (hint: Chapter 3). List them in a word document titled basic equipment. List all answers in this document.
  • Now that you know the three basic components, list what pieces of equipment you will need. 
  • For a room with 3 computers, what equipment will each computer need?
  • What piece of hardware is now needed to connect those three computers?
  • You should now know what equipment is required to connect 3 machines. What would you do to connect 25 machines? List answer in document.
  • You now have a list of what equipment is needed for each room with 3 machines and each lab with 25 machines.
  • Go to the Intel Networking Products page and look for a solution to connect a PRINTER to your network. What did you find?
Step 2 - Equipment
    • Using the basic equipment document as a template, create a new document called wiring. record all answers from step 2 in this document.
    • Use the floor plan, in the resources section, to figure out how many rooms need to be wired. How many classrooms need to be wired? Subtract 3 for use as computer labs. 
    • How many computers are needed for all the classrooms? (not including the 3 labs).
    • Add the 75 computers in the 3 labs. What are the total number of computers to be connected?
    • Using the floor plan. Figure out where you may want to place wiring closets. Using any of the resources listed, the classroom demonstration of equipping a wiring closet and the "field trip" to the main wiring closet in the school, list the required equipment in each of your wire closets. 
    • TIP: create each closet the same way, only the number of computers being connected should change.
Step 3 - Wiring
  • Record all answers in the wiring document from step 2
  • Now use the floor plan to sketch how you would run the wire between each wiring closet. 
  • What type of medium would you use to connect each closet? Refer to Quick Reference Guides to 100 Mbps Fast Ethernet.
  • What type of medium would you use to connect each room to the relative wiring closet?
  • How many computers can be connected to each segment?
  • You should now know where all wring connections are located.
Step 4 - Equipment Vendor
    • You now know all the equipment that you need, how many connections and where each connection is located. Now choose a vendor (click here for vendor references). Browse the vendor's product line a select the specific equipment that you need. Record this in a new document called vendor, use the same format as the previous documents.
    • List the vendor and products that you would use to satisfy the equipment requirements for each room, lab and wiring closet.
    • You may use more than one vender.
    • Try to justify your vendor choices.
Step 5 - Pricing
  • Record all pricing information in a document called pricing, use the same format as the previous documents.
  • Use the catalog sources to get pricing information. List source next to each price. you may use other sources. 
  • While finding prices for your vendor, notice the prices of similar products from other vendors. Where do your vendor prices rank? (high, low, about the same) 
  • In relation to the price ranking, justify your vendors prices. Take the following information into consideration during your analysis:
      • If high, is the product of higher quality? 
      • If low, is the product of lower quality? 
      • Are certain vendors over priced because of vendor label, but have similar performance to cheaper products?
      • Does vendor service and support have any affect? 
Step 6 - Create Presentation
    • Based on the information listed in the steps above, create a Power Point presentation to show your results to the class.
    • Include data recorded in the documents generated from the questions above.
    • You may include vendor logo's and quotes to support your equipment choices.

Evaluation
  • Power Point presentation 
  • Detailed equipment list, with separate price list.
  • Sketch of network layout.

Conclusion
In a short word document, answer the following questions.

1. After discussing your LAN model with the class; How can it be improved in comparison to the other groups presentations? How can the school's current networking technology be improved?

2. List some issues that you see with the current computer technology installed in the school. What do you think could be done to improve the current computer technology in the High School?
